is there a device that i can plug into my computer via usb2/3 that will allow me to play ps3 games in a window on my computer? i have no need to record gameplay, all i want to do is be able to play games with no lag in a window i can minimize, move around, and make full screen. I have read about the pvr and elgato devices, but none of them say if you can just play on screen with them. do any of you have any knowledge of this?
